Ok, I know it sounds like a stupid question but I really mean it.
This is a continuation to my post on why I'm bad at playing guitar.
I picked up a guitar 10 year ago and self taught myself. Being only 18 back then, it was more about "I want to play the guitar" rather than "I want to create music". I cared less if I will play Beethoven or AC/DC, I just wanted to play the guitar as a goal.
I started learning Flamenco for I thought it had unique and impressive techniques. I learned the techniques but had no idea what I am actually playing, was totally dependent on tabs and had zero interest in the Spanish culture on which Flamenco is heavily based on.
I struggled a lot and made poor progress, and eventually decided to move to western music and an electric guitar for it will be easier to a self taught person like myself. I played Surf music for again, it seemed cool and non-mainstream, but after some years it became dull and boring. I tried learning some theory and licks from rock and blues, but didn't persist much for I couldn't relate myself to the music.
People tell me to play the music I like listening to. The problem is that I listen very little to music nowadays, and if I do, it can be anything from Celtic tunes to KISS.
That said, I don't want to put down the guitar. I think that playing music is very beneficial to oneself (develops agility, coordination, ear and according to scientists is good fro the brain in general), but I simply can't find anything fun I want to play, focus on learning or actually caring about.
